About this trial
RINGQUEST is a Phase 2, open-label, single arm, basket, investigator-initiated clinical trial of sacituzumab tirumotecan in patients with:
* Cohort 1: papillary renal carcinoma (pRCC). * Cohort 2: less frequent bladder tumors such as variant histology urothelial carcinoma (VH-UC). The most common VH-UC are nested, microcystic, micropapillary, lymphoepithelioma-like, plasmacytoid, giant cell, poorly differentiated, lipid-rich, clear cell, sarcomatoid) bladder cancer and non-urothelial bladder cancer of epithelial origin including squamous cell carcinoma and adenocarcinoma (urachal and non-urachal).

Note: Participants with previously-treated brain metastases may participate provided they are radiologically stable (ie, without evidence of progression) for at least 4 weeks as confirmed by repeat imaging performed during study screening, are clinically stable, and have not required steroid treatment for at least 14 days before the first dose of study intervention.
